The origins of JIT: in the 1960s and 1970s, or in the 1980s as stated by Holweg (2006)?

The current article states that:

Its origin and development was in Japan, largely in the 1960s and 1970s and particularly at Toyota.[1][page needed], [2][page needed]

As neither of the two sources provide exact references, there is a source (Holweg 2006) that actually dates the origins of Just-in-Time to the 1980s:[3]

A second motivation for the underlying study came from my graduate students posing the simple yet logical question as to why the book by Womack et al. in 1990 had been so influential, given that major studies on just-in-time (JIT) manufacturing and the Toyota Production System (TPS) had been published by Schonberger, Hall and Monden almost a decade earlier (cf. Schonberger, 1982a; cf. Hall 1983a; Monden, 1983).

For this very reason, I've placed a {{Disputed inline}} after the two sources. Cheers! Jayaguru-Shishya (talk) 23:43, 23 August 2017 (UTC)

Okay, I am starting to get a grip on this. Indeed, it may be so that the origins of JIT (which is used synonymous to the Toyota Production System together with lean) lies in the Japanese automotive industry of the 1960s. However, the first English source of JIT/TPS is from 1977, and a wider academic interest in the West arouse in the beginning of the 1980s. However, an exact date is hard to point when JIT/TPS can be seen born in Japan, but the earliest Japanese-language documentation dates back to 1965. This all according to Holweg (2006) quoted above.
I will implement the required changes while a have more time; I'm rather occupied all the way till July 31st, after which I'll be on vacation. 8-D Jayaguru-Shishya (talk) 13:28, 30 May 2018 (UTC)
